Why won't Simulink Onramp launch?

Hello,

Whenever I attempt to launch Simulink Onramp, I recieve an error saying "Simulink Onramp failed to launch. The system temporary folder is a subfolder of 'CacheFolder', which is not supported. Change the 'CacheFolder' so it is not a subfolder of the system temporary folder." I cannot find 'CacheFolder' through searching the computer, and I do not know how to change this subfolder. How can I fix this error?

The 'CacheFolder' mentioned is from Simulink preferences > General.

More details on it are given in this section from the page on Simulink general preferences. Like it mentions, the setting is empty by default and that means that the Cache Folder uses the present working directory (pwd). You could try either of the following:

1. Verify whether your current directory is under the temp folder. Change the pwd to a folder that is not under the temp folder.
2. Manually set the Cache Folder under Simulink general preferences.

Here's how to get details about the current Cache Folder programmatically: Get File Generation Control Parameters

Here's how to modify the Cache Folder programmatically: Set File Generation Control Parameters

You can use tempdir to see the System Temp Directory.

%

myCacheFolder = fullfile('C:','aNonDefaultCacheFolder');

myCodeGenFolder = fullfile('C:','aNonDefaultCodeGenFolder');

Simulink.fileGenControl('set', ...

'CacheFolder',myCacheFolder, ...

'CodeGenFolder',myCodeGenFolder, ...

'keepPreviousPath',true, ...

'createDir',true);

Thanks a lot!!

% 
myCacheFolder = fullfile('C:','aNonDefaultCacheFolder');
myCodeGenFolder = fullfile('C:','aNonDefaultCodeGenFolder');
Simulink.fileGenControl('set', ...
    'CacheFolder',myCacheFolder, ...
    'CodeGenFolder',myCodeGenFolder, ...
    'keepPreviousPath',true, ...
    'createDir',true);

copy the code above then paste into matlab code area and run it.

You can just change your current working space directory.

[Florian Schallinger]

How can you do that permanently? When I copy/pasted the code from above, I had to do it again ont the following bootup of the programm.

[Ugur]

You can set the file directories in Simulink->Preferences.

I used the files created by the provided by from other comments in this thread.
